Our 100.0 release doesn't include 64-bit native libraries, but 64-bit devices run 32-bit libraries OK. However, if the OS loads another dependency that does have 64-bit libraries, prior to loading our SDK, then the OS will be looking for 64-bit libraries for all other dependencies, which means loading our 32-bit native library (libruntimecore_java.so) will fail at runtime. Hence Alexander Nohe asking about dependencies, above. A solution to this general problem is to filter out 64-bit native libraries from the APK, so the OS is then expecting all libraries to be 32-bit. We're considering including 64-bit specific libraries in future releases.
